Welcome holedigger. I have the DFX and it is an excellent weapon lol To save some of your programs, just pick a stock program and load it as usual, balancing it and so forth. I use the coin and jewelry factory preset since it has a lot of the settings I like. Then go into the menu and alter any settings in audio, disc, etc... until you have a good program. Just quickly click and release the trigger and you are ready to temporarily hunt with the new settings. To keep it in a program slot, just hit menu, then hit enter preset programs and then scroll down past the program labeled prospecting. The EEProm programs after the prospecting program are the ones you can store your new program in. Now enter any one of those four. You will see load, save, name. Scroll down to save and hit enter. It will blink and you have just over written the previously saved program, I now scroll down to name, so I can name it. It takes a while to name it, but it's worth it. lol When you are done, just load it and re check to see if all the settings are the ones you chose. You can override any of those 4 programs anytime you want, just in case you make minor changes that you like better. Hope this helps.....and if you really want to know the indepth DFX info?? Jeff Foster's book is unreal. If you have any problems saving a program, just ask again or PM me.
